Yes, I would also like to have a comment from Simon on this.
I've asked Simon a few times in the past days. But I would really
like to see these driver changes integrated in this release.
If Simon (or somebody else) has some better ideas to handle this,
I can provide some follow-up patches.
Thanks,
Stefan
